U.S. Army Public Health Center Toxicology Lab technician assessing samples. Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.
Methionine ball and stick model spinning. Methionine (symbol Met or M) [3] (/ m ɪ ˈ θ aɪ ə n iː n /) [4] is an essential amino acid in humans.. As the precursor of other non-essential amino acids such as cysteine and taurine, versatile compounds such as SAM-e, and the important antioxidant glutathione, methionine plays a critical role in the metabolism and health of many species ...
The Draize test is an acute toxicity test devised in 1944 by Food and Drug Administration (FDA) toxicologists John H. Draize and Jacob M. Spines. Initially used for testing cosmetics, the procedure involves applying 0.5 mL or 0.5 g of a test substance to the eye or skin of a restrained, conscious animal, and then leaving it for a set amount of time before rinsing it out and recording its effects.

Another study evaluated doses of 1g and 3g and showed improvements in wrinkles, firmness, and hydration at both dose levels in 20 persons. [29] The same author published a study on MSM for hair and nails from the same clinical trial. The results showed improvements in hair shine, volume, and appearance, and nail shine and appearance.

This type of toxicity test uses organisms in their most sensitive life stages, usually during times of early reproduction and growth, but not juveniles. [3] The MATC is the highest concentration that should not cause chronic effects, however, for regulatory purposes, a maximum concentration to protect against acute effects must exist as well.
